Attention to the common faults of pneumatic control valve during use
Many users who use pneumatic control valves may encounter such problems. When using them, almost most users will present problems of this kind or that kind. Don’t worry, these problems you are worried about will be easily solved in the pneumatic control valve. What to do when the valve does not work.
1. First check whether the solenoid valve is normal, whether the coil is burned out, whether the solenoid valve core is blocked by stolen goods and slag, if this is the case, I suggest that your solution is: replace the solenoid valve, replace the coil with the pneumatic control valve , Get rid of the stolen goods.
2. What to do if the pipeline is distorted or squashed.
The professional manufacturer will tell you the solution. The best way is to correct or replace the pipeline to solve the actual problem.
3. If it appears that the handle is in the manual position, the user must pull the handle to the pneumatic automatic position.
4. If there are impurities in the valve that will jam the ball core and stop running, remove the impurities and replace the damaged valve or component, the electric regulating valve.
5. When the winter is cold, the ambient temperature is relatively low, which is very simple to cause the pipeline to freeze, so the user must add water removal equipment.
With the development of my country’s industry, pneumatic control valves have become more and more widely used in metallurgy, petroleum, chemical and other fields. The operating conditions of pneumatic control valves will directly affect the process of automatic control. Therefore, in addition to the correct use of Quality and perfect after-sales service are also what valve manufacturers need to pay attention to. When using pneumatic control valves, you should pay attention to the following matters:
1. In order to ensure the normal operation of the pneumatic control valve, the new valve should be checked whether the nameplate on the valve meets the planning requirements before use.
2. Experiment on the pneumatic control valve: basic error limit, total stroke deviation, return difference, dead zone, leakage (check strictly required working conditions).
3. If the pneumatic control valve of the original system is to be repaired, in addition to the above-mentioned verification, the old valve packing and sealing joint number should also be checked.
